2. ENG2000: R.I. Hornsey Intro: 2 What’s in ENG2000? Split into two parts …  Materials Science & Engineering  Management and Economics of Engineering Design Projects Intended to cover technical material of relevance to all engineers  part of the engineer’s “general knowledge” of how the world works  tools for working in engineering Also contains a design and construction project  predict performance of your design before demonstrating it  meet cost and performance targets

3. ENG2000: R.I. Hornsey Intro: 3 Part I: Materials Science & Engineering Properties of Materials  atomic structure and bonding  crystals, defects, failure  mechanical properties of metals  alloys, ceramics, polymers Electronic Properties of Materials & Applications  electrical  thermal  magnetic  optical Mechanics of Materials  stress, strain, E, torsion, shear etc.  beams, simple trusses etc.  pressure vessels

4. ENG2000: R.I. Hornsey Intro: 4 Management and Economics of Engineering Design Projects Engineering Economics  time value of money  cash flow analysis  comparison methods  depreciation and financial accounting  replacement decisions  taxes Management and Safety for Engineers  estimation - BOTE  project management  meetings  workplace safety - WHMIS (2 classes), Ontario Health and Safety Act (2 classes)

5. ENG2000: R.I. Hornsey Intro: 5 I’m a Computer Engineer Space Engineer Geomatics Engineer Engineering Physicist Why do I need to know anything about materials and structures?

6. ENG2000: R.I. Hornsey Intro: 6 Materials – the global perspective The characteristic that defines humanity is not the use of tools but the understanding of materials Properties of interest include(d):  strength & weight  sharp edges  insulation  workability It is discoveries of “new” materials that have shaped history  flint & glass  soft metals (copper, tin, lead)  alloys (bronze)  iron

7. ENG2000: R.I. Hornsey Intro: 7 More recently steel scientific study of elements mass production of steel radioactive elements semiconductors plastics These factors continue; improvements in the understanding and preparation of materials drives today’s technology: semiconductors (Si, GaAs, GaAsP, InGaAs, SiGe...) better insulators better fabrication better magnetic films better optical properties conducting and light-emitting polymers amorphous and polycrystalline

9. ENG2000: R.I. Hornsey Intro: 9 Ok – but I still want to know why a knowledge of materials is relevant to me! We all use computers every day... Let’s see how many materials we need to use a computer...  Chips: crystalline Si, SiO2, poly-Si, aluminum, boron & phosphorus doping, adhesives, ceramic package, all materials & chemicals required to make all of the above  Other electronics: quartz, copper, carbon, dielectrics, plastic & ceramic insulators, circuit board (fibreglass), solder (lead & tin), ferrite transformer core, gold- plated electrodes  Disk drive: magnetic motor components, magnetic films

10. ENG2000: R.I. Hornsey Intro: 10  CD ROM: optical lenses, laser components, reflective cd film  Monitor: glass, phosphors, tungsten filament  Communications: Fibre-optic cable, transmitter, receiver, amplifiers  Mechanical: plastics, steel, copper, aluminum  Plus: all the materials needed to generate and transmit power all the materials required by telephones all the materials for building & furniture, ventilation etc!

11. ENG2000: R.I. Hornsey Intro: 11 Mechanics of materials The previous examples were primarily ‘electronic’, but mechanical structures are equally important An elementary knowledge of structures – the ‘mechanics of materials’ – is vital to all engineers  computer engineers often end up designing control systems for complex mechanical systems cars, space shuttle, flexible robotic systems  for space engineers, the mechanics of the satellite or space vehicle are critical to the design of all systems  the expertise of geomatics engineers is frequently used for locating and monitoring engineering structures  mechanical properties of materials – and how to improve them – are the domain of the engineering physicist

12. ENG2000: R.I. Hornsey Intro: 12 Purpose of ENG2000 pt.I Each material and structural design is used because of its specific properties In order to design and use these materials effectively – which makes us humans superior to, say, my cat – we must know what these properties are and how to control them Therefore, we need to understand the factors that determine these properties Then we need to know how to optimise use of the materials in engineering applications

14. ENG2000: R.I. Hornsey Intro: 14 Fall Term Team Project (15%)  design and analyse a crane structure to carry a load of 1,800kg (equivalent to a Lexus SUV) at a height of 50m, and at a horizontal distance of 25m from the base. Exam (35%)

15. ENG2000: R.I. Hornsey Intro: 15 Winter Term Project (50%) In teams of four, design, construct and demonstrate a flying vehicle to travel at least 10m. The total cost of the project components is limited to CDN$10 (including any failed designs).  Prizes will be awarded to the team landing closest to a target at 15m, to the lightest machine, and to the most aesthetically pleasing entry.  Requirements will include: a proposal, a progress report, a final report and presentation, and the demonstration. Emphasis will be placed on the design process, calculations (rather than trial and error), and predictions of performance, as well as project planning and documentation. Full rules and requirements to be announced.
